滚管技术
Using self-boring grouted rock external screw bolt to build geotechnical anchor, is the key technique by which resolve the difficulty of the construction in complex geologic circumstances. And external screw steel tube rolling is the key equipment to manufacture finish rolling external screw steel tube.
使用自钻注浆式外螺纹锚杆进行岩土锚固施工,是解决复杂地质条件施工难题的关键技术,而外螺纹钢管轧机则是生产精轧外螺纹钢管的关键设备。
So based on these industrial statuses in this paper, through the numerical simulation method, the rolling bending technique has been researched in spiral tube forming processing, in order to reduce costs and increase product qualities further.
在此工业背景下,本文采用计算机数值模拟方法,研究螺旋盘管滚弯成形技术,以期进一步降低生产成本,提高螺旋盘管成形质量。
